Title: Influence of alcohol on the contractile properties of skeletal muscle Objectives: To identify the impact of alcohol to contractile attribute (Tc - contraction time and Dm - maximal displacement) m. rectus femoris. Method: The diploma thesis corresponds with empirically-theoretical based study. The research has a character of a quasiexperiment. The measured participants were consisted of students (n = 8) of Military Department (VO) and students (n = 3) of civilian (TVS) of attending full-time studies at the Faculty of Physical Education and Sport (FTVS) of Charles University (UK) in Prague. There were used the methods of descriptive statistics to describe it - rate position (arithmetic mean) and a measure of variability (standard deviation). Contractile attributes (Tc, Dm) were measured on the device TGM 100 at an electricity current intensity 80 mA. To analyse the normality of data was used Kolmogorov-Smirkov's test. For further calculations was used parametric method one-way ANOVA for repeated measurements were used statistical significance. For statistical processing was used computer program IBM SPSS Statistics 22 and the individual dose of alcohol relative to body weight was administered in three rounds at 20 minute intervals. Results: The average Tc was 33.23 ± 3.45 ms for the first. ; Název: Vliv alkoholu na kontraktilní vlastnosti kosterního svalstva Cíl práce: Cílem práce je zjištění vlivu alkoholu na kontraktilní vlastnosti (Tc a Dm) m. rectus femoris. Metoda: Jedná se o práci empiricko - teoretickou, kde má výzkum charakter kvaziexperimentu skupiny 11 probandů s experimentálním způsobem získávání dat. Sledovaný soubor tvořili studenti VO (n = 8) a studenti TVS (n=3) navštěvující prezenční formu studia na UK FTVS. Pro charakteristiku souboru byly použity metody deskriptivní (popisné) statistiky - míra polohy (aritmetický průměr) a míra variability (směrodatná odchylka). Kontraktilní vlastnosti (Tc, Dm) byly měřeny přístrojem TMG 100 při intenzitě elektrického proudu 80 mA. Normalita dat byla ...
